Abstract

An influential strand of research has tested for the effects of immigration on natives' wages and employment using exogenous refugee supply shocks as natural experiments. Several studies have reached conflicting conclusions about the effects of noted refugee waves such as the Mariel Boatlift in Miami and post-Soviet refugees to Israel. We show that conflicting findings on the effects of the Mariel Boatlift can be explained by a large difference in the pre- and post-Boatlift racial composition in subsamples of the Current Population Survey extracts. This compositional change is specific to Miami, unrelated to the Boatlift, and arises from selecting small subsamples of workers. We also show that conflicting findings on the labor market effects of other important refugee waves are caused by spurious correlation between the instrument and the endogenous variable introduced by applying a common divisor to both. As a whole, the evidence from refugee waves reinforces the existing consensus that the impact of immigration on average native-born workers is small, and fails to substantiate claims of large detrimental impacts on workers with less than high school.

Abstract

This paper uses a new database to establish two findings covering the first globalization boom before World War I, the second since World War II, and the autarkic interlude in between. First, there is strong evidence supporting a Tariff-Growth Paradox: protection was associated with fast growth before World War II, while it was associated with slow growth thereafter. Second, there is strong evidence supporting regional asymmetry: while the tariff-growth association was powerful and positive in the Core and rich New World before World War II, it was typically weak and negative in the poor Periphery. The paper offers explanations for the Paradox by controlling for a changing world economic environment. It shows how the oft-quoted Sachs-Warner results for 1970-1989 are significantly revised when one controls for trading partners' growth, trading partners' tariffs and the effective distance between them over the longer half-century 1950-1997. Falling partners' tariffs was the most important force accounting for the switch in sign on the tariff-growth connection after 1950. An increase in own tariffs after 1950 hurt growth, but it would not have hurt growth in a world where partners' tariffs were much higher, trading partners' growth much slower, and the world less closely connected by transportation. World environment matters. Leader-country reaction to big world events (like the Great Depression) matter. Followers take notice.

Abstract

The U.S. limits work visas for low-skill jobs outside of agriculture, with a binding quota that firms access via a randomized lottery. We evaluate the marginal impact of the quota on firms entering the 2021 H-2B visa lottery using a novel survey and pre-analysis plan. Firms exogenously authorized to employ more immigrants significantly increase production (elasticity +0.16) with no decrease or an increase in U.S. employment (elasticity +0.10, statistically imprecise) across several pre-registered subsamples. The results imply very low substitutability of native for foreign labor in the policy-relevant occupations. Forensic analysis suggests similarly low substitutability of black-market labor.

Abstract

A decade has passed since Robert Lucas asked why capital does not flow from rich to poor countries. Lucas used a contemporary example to illustrate his Paradox, the very modest flow of capital from the United States to India during the second great global capital market boom, after 1970. Had he paid more attention to the first great global capital market boom, after 1870, he might have been less surprised. Very little of British capital exports went to poor, labor-abundant countries. Indeed, about two-thirds of it went to the labor-scarce New World where only a tenth of the world's population lived, and only about a quarter of it went to labor-abundant Asia and Africa where almost two-thirds of the world's population lived. Why? Was it caused by some international market failure, or was it due to some shortfall in underlying economic, demographic or geographic fundamentals that made capital's productivity low in poor countries? This paper constructs a panel data set for 34 countries who as a group got 92 percent of British capital, and uses it to conclude that international capital market failure (including whether the country was on or off the Gold Standard) was not involved. It then ranks the three big fundamentals that mattered schooling, natural resources and demography.

Immigration Restrictions as Active Labor Market Policy : Evidence from the Mexican Bracero Exclusion

Abstract

There has been little rigorous evaluation of immigration barriers intended to improve domestic terms of employment by shrinking the workforce. We study one such barrier, a policy change that excluded almost half a million Mexican bracero seasonal agricultural workers from the United States. Using novel data to measure state-level exposure to the policy, we reject the wage effect of bracero exclusion predicted by theory in the absence of induced technical change. We fail to reject the hypothesis that exclusion did not affect U.S. agricultural wages or employment. Important mechanisms include adoption of less labor-intensive technologies and shifts in crop mix.

Abstract

Despite an enormous literature that has analyzed the comparative experiences of Latin America and Asia in post-World War II trade policy, almost no attention has been paid to the comparative experience prior to the wars. Even a cursory look at the best available empirical evidence reveals tremendous contrasts between the two regions. Latin America had the highest tariff barriers on earth before 1914; Asia had the lowest. Protected Latin America's belle ,poque also boasted some of the most explosive growth performance on earth, while Asia registered some of the worst. What brought the two regions to the opposite ends of the tariff policy spectrum? And why are these quantum differences in economic performance so at odds with postwar conventional wisdom? We begin by describing a novel tariff database we have constructed from largely original sources. We explore the impact of colonial rule and unequal treaties' on Asian tariffs, as well as the impact of geography and political economy on Latin American tariffs. Limits to tariff policy autonomy explain one third of the vast difference between the two regions' tariffs before 1914; differences in the extent and structure of internal markets as well as the world tariff environment explain much of the rest. We conclude with an agenda for the future.

Abstract

This paper uses a new database to establish a key finding: high tariffs were associated with fast growth before World War II, while associated with slow growth thereafter. The paper offers some explanations for the sign switch by controlling for novel measures of the changing world economic environment. Rejecting alternative explanations based on changing export market growth or transportation cost declines, it shows how the oft-quoted Sachs-Warner result might be turned on its head in a world environment characterized by a moderately higher level of generalized tariff protection. We confirm the spirit of recent findings by Rodrik and Rodr¡guez that postwar tariffs need not be negatively correlated with growth in an unconditional fashion. Just a 4% increase in average tariff rates among trading partners might suffice to reverse any negative relationship between an average country's tariffs and its growth. An increase in own tariffs after 1970 hurt or at least didn't help growth, but it would have helped growth in a world where average trading partners' tariffs were moderately higher. The world environment matters. Leader-country reaction to big world events matters.
